========================================================================
== UPDATE HISTORY ==
2018-02-20 // Nibaldo González <nibgonz@gmail.com>
Fix '$' symbol, highlighted as 'dsError' by C++ (isocpp.xml).
Update syntax for Bison (3.0.4):
- Add declarations, directives in rules and the '@' variable.
- Allow a tag in '%union', declarations in multiple lines and
grammar declarations in the grammar rules section.
- The ';' char is not necessary to finish a rule. Allow '; |'
within rules.
Add mimetypes and extensions '*.ypp' & '*.y++'.
2007-10-01 // Sebastian Pipping <webmaster@hartwork.org>
Added: Extension "*.yy" for Bison
2004-05-26 // Jan Villat <jan.villat@net2000.ch>
YACC.XML 1.00 - First released.
